Abstract: We present an analysis of archival NGC 5548 Hbeta line profile data. 
Using a random-walk interpolation method to patch gaps in the time series,
we computed standard CCFs and find: (1) differential measurements show
the blue wing lags the red wing, indicative of inflow; (2) the blue/red 
wing ratio correlates with luminosity; and (3) the blue/red wing 
variations provide evidence of structural changes in the BLR on the 
dynamical timescale. We also examine the CIV profile in IUE observations 
of NGC 7469 and find similar results.
